Compare the oil- or gas-generating potential of the different source rocks

rock-Eval data generated for petroleum source rocks (or low permeability reservoir rocks) in Montana (from a U.S. Geological Survey database). It is your task to:

  • Calculate values (Hydrogen index, Oxygen Index, and others) and create:
    • modified van Krevelen diagrams showing the data for all source rocks
      • Hint: compare the values on the axes to the “modified Van Krevelen diagram” in the notes!
    • S2 vs TOC plot like those shown in the 1990 AAPG article
    • Pyrolysis Tmax versus HI as shown in lecture notes
  • Compare the oil- or gas-generating potential of the different source rocks (the geologic names of the formations are given), and
  • Summarize what you can from the data analysis by answering questions on Moodle > Assignments > Homework – Rock Eval
